Family and property records identified the officer as 43-year-old Rosette Samuel, the Associated Press reported. She was a member of the 108th precinct in Queens for at least the past 13 years, police said.

Authorities identified the man as Dason Peters and the infant as Dylan, the AP reported. Peters is believed to be in his 30s and is the father of the baby boy, police said.

The teenager, who is the officer’s son from a previous relationship, was uninjured.

“He ran for his life,” said a neighbor and friend of the teen Saladine Bell.

Neighbors said they can’t believe Samuel may have carried out the double murder-suicide.
